GripWalk:
The sole-binding system for better walking comfort and top skiing performance. GripWalk contains of a new co-polymer sole with rocker profile. The convex shape and ribbed tread of the rubber add a lot of walking comfort and provide a much better grip. Still, integrated pads made of stiff and rigid materials, enable great power transmission and more precise release function of the binding. GripWalk soles are the perfect tuning parts designed for selected premium ski boots and bindings.
TRUST A PROFESSIONAL:
Before using your new boots, you must have an authorized K2 Ski retailer check your boot, binding, and sole setup. K2 Ski boot soles must only be changed by an authorized retailer.
